Abstract (en)
[origin: US10111015B2] A hearing aid (21) includes a signal processor producing signals that have been processed to compensate for a hearing impairment, a first output converter (26), a second output converter (27), a first acoustic output transducer (34) and at least a second output transducer (35). The first output converter (26) and the first output transducer (34) are configured to reproduce the high frequencies of the processed signals, and the second output converter (27) and the second output transducer (35) are configured to reproduce the low frequencies of the processed signals. The output converters (26, 27) may preferably be embodied as direct digital drive output converters. The processed signals are split between the first and second output converters according to a cross-over frequency tunable by programming.
